On the Number of Shortest Weighted Paths in a Triangular Grid

open access: yesMathematics, 2020
Counting the number of shortest paths in various graphs is an important and interesting combinatorial problem, especially in weighted graphs with various applications. We consider a specific infinite graph here, namely the honeycomb grid. Changing to its

Optimization of transport protocols with path-length constraints in complex networks [PDF]

open access: yes, 2010
We propose a protocol optimization technique that is applicable to both weighted or unweighted graphs. Our aim is to explore by how much a small variation around the Shortest Path or Optimal Path protocols can enhance protocol performance.

Non-crossing Rectilinear Shortest Minimum Bend Paths in the Presence of Rectilinear Obstacles

open access: yesJournal of Telecommunications and Information Technology, 2018
The paper presents a new algorithm to determine the shortest, non-crossing, rectilinear paths in a twodimensional grid graph. The shortest paths are determined in a manner ensuring that they do not cross each other and bypass any obstacles present. Such

Distributed Approximation Algorithms for Weighted Shortest Paths

open access: yes, 2014
A distributed network is modeled by a graph having $n$ nodes (processors) and diameter $D$. We study the time complexity of approximating {\em weighted} (undirected) shortest paths on distributed networks with a $O(\log n)$ {\em bandwidth restriction} on

Engineering Shortest Path Algorithms [PDF]

open access: yes, 2004
In this paper, we report on our own experience in studying a fundamental problem on graphs: all pairs shortest paths. In particular, we discuss the interplay between theory and practice in engineering a simple variant of Dijkstra’s shortest path algorithm.

Physarum can compute shortest paths [PDF]

open access: yesJournal of Theoretical Biology, 2012
Physarum Polycephalum is a slime mold that is apparently able to solve shortest path problems. A mathematical model has been proposed by biologists to describe the feedback mechanism used by the slime mold to adapt its tubular channels while foraging two food sources s0 and s1.

Observer of changes in the forest of the shortest paths on dynamic graphs of transport networks

open access: yesДоклады Белорусского государственного университета информатики и радиоэлектроники, 2020
The purpose of the work is the development of basic data structures, speed-efficient and memoryefficient algorithms for tracking changes in predefined decisions about sets of shortest paths on transport networks, notifications about which are received by

Shortest Path Algorithms for Pedestrian Navigation Systems

open access: yesInformation, 2022
Efficient shortest path algorithms are of key importance for routing and navigation systems. However, these applications are designed focusing on the requirements of motor vehicles, and therefore, finding paths in pedestrian sections of urban areas is ...

Shortest-Path Reconstruction Algorithms [PDF]

open access: yesThe Computer Journal, 1993
Summary: We study the problem of computing shortest paths between pairs of vertices in an \(n\)-vertex graph, given only the all pairs shortest paths distance matrix. This computation is called a reconstruction, since the algorithm has no access to explicit information about edges in the original graph. We present the following results: 1.

ARP-Path: ARP-Based, Shortest Path Bridges [PDF]

open access: yesIEEE Communications Letters, 2011
This letter is a summary proposal for an evolution of the Ethernet transparent bridge paradigm that provides simple, shortest path bridging in campus networks. ARP-Path Ethernet Switches set up an on-demand path between two hosts just reusing and flooding the standard ARP request frame through all links and confirming the path reaching to the ...
